Are there any specific server configurations or settings that need to be adjusted to ensure successful Wake-on-LAN functionality with PHP?

To ensure successful Wake-on-LAN functionality with PHP, you may need to adjust the server's network settings to allow for Wake-on-LAN packets to be sent and received. Additionally, you may need to configure the server's BIOS settings to enable Wake-on-LAN functionality. Once these configurations are in place, you can use PHP to send the Wake-on-LAN magic packet to wake up a remote computer on the network. 

// Function to send Wake-on-LAN magic packet
function wakeOnLan($macAddress, $broadcastAddress) {
    $macAddressHex = str_replace(':', '', $macAddress);
    $magicPacket = pack('H12', 'FFFFFFFFFFFF') . str_repeat(pack('H12', $macAddressHex), 16);
    
    $socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
    socket_set_option($socket, SOL_SOCKET, SO_BROADCAST, 1);
    socket_sendto($socket, $magicPacket, strlen($magicPacket), 0, $broadcastAddress, 7);
    socket_close($socket);
}

// Usage example
$macAddress = '00:11:22:33:44:55';
$broadcastAddress = '255.255.255.255';
wakeOnLan($macAddress, $broadcastAddress);
